have invented certain newanduseful'hn movements in' Hydrocarbon Motors., of x'vhichfthe following'isaspecifieation; This invention i relates' to.v hydrocarbon motors, and particularly to the-construction'- and arrangement of the cylinders, intake passages, and carburetor and heat-ing` means. Onofn the; objects o f-the invention is to provide an eiiicient heating means for the intake conduit, arranged to prevent the loss of heat therefrom. j

Another object of the invention is to provide, a V-type motor withan outside carburetor and efficient intake passages therefrom to the cylinders. l

Other objects of the invention will appear from the following description taker. in connection with the drawings which form a part of this specification, and in which- Figure 1 is a front elevation and transverse section of a hydrocarbon motor embodying the invention; and

Figure 2 is a side elevation -of the motor shown in Figure 17 'with one of the cylinder blocks removed, and with parts shown 1n section. I Referring to the drawings, 10 represents the crank case of a hydrocarbon motor, upon which are mounted, in the form shown, two cylinder blocks 11 and 12. Eachpf these blocks comprises six cylinders with suitable water jackets and with suitable valves and intake and exhaust passages. One of the exhaust valves is shown at 13, in Figure 1, and a longitudinally extending intake passage is shown at 14: and an exhaust pipe for each cylinder block at 15. Each of the blocks is provided with a cylinder head 16 properly secured to it as by bolts 17.

The intake and exhaust manifolds or passages, above referred to, are arranged on the inside of the cylinder blocks, and the intake passages are supplied from a carburetor 18 arranged on one of the outer sides of the motor. Thus ,the carburetor is accessible and it is also far enough away from the excessive heat of the exhaust pipes toinsure that there will be no boiling of its fuel.

In order that the mixture from the carburetor to the intake manifolds 14 may pass 4, 1920, semaine/1983236.

` intake manifolds..4 The upper ende of .he

Conduit 19 is inthe formv of a 7l,y as shown i at 20, and the two branches of the F are connected to the respective intake manil foldsl4..` i @ne vof the cylinder `bl0,cl:s,:the v block 12 in the form showny is formed with a transverse passage 21 between two of its cylinders, preferably cylinders Sfand 1, to make room for the conduit 19, and since this passage 21 is below the water jacket of the cylinder block, it takes up very little room longitudinally of the block.

It is desirable that the mixture passing to l the motor shall be heated to facilitate vaporization and prevent condensation. The

pipe or conduit 19, therefore, is providedy with a heating jacket 22, most of which is on that portion of the pipeV arranged in the passage 21 so that there is very little dissi- .pation of heat from the jacket. Infact the passage 21 is kept hot from the heat of the cylinder walls, and, therefore, practically all of Vthe heat of the heating jacket `22 passes inwardly to the intake pipev 19 through which the mixture passes.

The mixture heater shown is of the combustion type, and it comprises, in addition to the jacket 22, which has an'outlet 23 into the intake pipe 19 above a throttle valve 24, a combustion chamber 25 in communicav tion with the jacket 22, a passage 26 leading from the `carburetor 18 to the combustion chamber 25, and a spark Iplug 27 for firing the charge of mixture vwhich, enters the chamber 25 through the passage 26. It will be noted that the inlet end 28 of the passage 26 is arranged at the elbow forming the connection between the upper end` of the carburetor, 18 and the conduit 19, and it is found that this arrangement provides a good mixture for the combustion heater.

In operation, when the throttle valve 24 is.l nearly closed for idling, the high suction in the intake pipe 19 is communicated to the jacket 22 and chamber 25 through the opening 23,'and thus a suitablemixture is drawn from the carburetor 18 through the passage 26 into the combustion chamber 25. y

19 `where it mixes with the incoming mixture' for theinotor cylinders. The incoming mixture, therefore, is heated both by the heat from thejacket 22 and by direct con-` tact with the hot gas which passes into the conduit 19 from thecombustion heater.

A specific embodiment `of the invention has vbeenl described in detaily and will Abe specifically claimed, but-it will lbe* under stood thatthe invention is not limited to the exact details of construction shown, as itwiil be apparent that changes may` bemade without departing from the spirit or scope of the invention. y j

I-Iaving thus describedv my invention, what I claim and desire tov secure by Letters Patent is:

1.' In aV- type hydrocarbon motor, the combinationjwith two cylinder blocks havextendingthrough one ofsaid blocks on an 7incline and connected at its upper end vto saidlintake passages, a carburetor connected toV the lower end of said conduit, anda heater jacket von the inclined part of said conduit. n e

2. In a hydrocarbon motor, the combination with ya cylinder block having a transverse passage between twoof the cylinders, of an intake pipe extending throughl said passage and having a heating jacket in the passage. f e l f v3. In a V-type'hydrocarbon motor,'the combination withV a cylinderl block thereof, of an intake conduit extending through' the blockon an incline, acarburetor connected to the "conduit, andv a combustion yheater device connected to the conduit at the angle between the carburetor vand the conduit.

Intestimony whereof I aix. my signature. JESSE G. VINCENT.
